PRB: Check Boxes Don't Display in Certain Situations

ID: Q130729

The information in this article applies to:

SYMPTOMS

You aren't able to see a check box or radio button when it is highlighted (selected) except for the outline around the object.

CAUSE

You may be using an incompatible color combination of the pen and fill colors for the object that nullifies the display of an element like an X in a check box, and the mode of the get object(s) may be set to TRANSPARENT.

WORKAROUND

Ensure that the GET object is marked as OPAQUE and that your color combinations do not conflict with each other. For example, a white fill color would conflict with a white pen color.

STATUS

This behavior is by design.
